“…The range of sediment hydrocarbon concentrations measured in the expanded study area used in ANIMIDA III was comparable to that measured in the earlier BSMP and ANIMIDA projects, and in other similar Alaskan Arctic locations (Harvey et al ; Kasper et al ). The hydrocarbon data also are comparable, on a station‐specific basis, for stations that have been monitored over many years.…”

The United States Bureau of Ocean Energy Management (BOEM) has sponsored 4 major monitoring projects in the oil and gas development area of the Alaskan Beaufort Sea since the 1980s, the last being the Arctic Nearshore Impact Monitoring in the Development Area III (ANIMIDA III) Project (2014–2017). These studies were conducted to better understand the physical, chemical, and biological environments and how oil and gas activities may impact them. This paper focuses on monitoring sediment hydrocarbon chemistry. The projects included measuring polycyclic aromatic hydrocarbons (PAHs), n‐alkanes and isoprenoids (SHCs), and sterane/triterpene (S/T) geochemical biomarkers and determining their distribution, possible sources, and environmental significance in the sediments of the Beaufort Sea and rivers emptying into it. Concentrations of hydrocarbons in sediments were variable on both spatial and temporal scales; surface sediment concentrations of total PAHs (TPAHs), the class of hydrocarbons of greatest environmental interest, averaged between 300 and 700 μg/kg in different years of monitoring between 1985 and 2015. The concentrations were similar to those measured in other marine regions of Alaska where oil activities have not occurred. Sediment TPAH concentrations were below sediment quality guidelines values, indicating a low risk of harm to benthic marine communities. The hydrocarbons in the Beaufort Sea sediments are primarily from non‐oil petrogenic and biogenic sources, with small amounts of pyrogenic hydrocarbons. Most of the hydrocarbons are carried to the Beaufort Sea in coastal erosion and river inputs of hydrocarbon‐rich materials, such as peat and shale. The majority of the Beaufort Sea Development Area, including near production facilities, contains uncontaminated sediments with only a few small areas near (<100 m) some exploratory wells where petroleum hydrocarbon concentrations are above regional background.

“…Moreover, although only two alkyl-PAHs were measured in this study (1-MN and 2-MN), they were more abundant than their parent PAH (Nap) at all locations along the cruise (Figure 2). Previous studies indicate that the alkyl-substituted PAHs in sediment are likely derived from petrogenic inputs and this dominance of alkyl-PAHs has been previously reported in sediments collected from the northeastern Chukchi and Beaufort Sea shelves (Harvey et al, 2014;Yunker et al, 1996). Although it varies with sampling location, Adhikari et al, 2015Adhikari et al, , 2016 have reported that the alkylated PAHs contribute to the major vertical fluxes and also contribute significantly to the PAHs distribution in the northern Gulf of Mexico sediments even in natural background conditions (Adhikari et al, 2015;Adhikari et al, 2016).…”

“…However, concentrations of atmospheric heavier 5-6 ringed PAHs, which were mainly detected in the particulate phase, were quite low, while their levels were extremely low in surface seawater (Ma et al, 2013). Therefore, similarities in the PAH profile between the atmosphere, surface seawater and benthic sediments are apparent for the low MW PAHs only, although it is difficult to ascertain the influence of atmospheric sources on the PAHs present in benthic sediments, especially given water column 'processing' prior to and during particle settling (Harvey et al, 2014).…”

Although PAHs represent only a small fraction (0.2-7%) of the total composition of crude oil, their relative persistence in the environment and potential toxicity to marine organisms warrants research into their sources and fate in marine systems (Harvey et al, 2014).…”

Eighteen polycyclic aromatic hydrocarbons (PAHs) were measured in surficial sediments along a marine transect from the North Pacific into the Arctic Ocean. The highest average Σ 18 PAHs concentrations were observed along the continental slope of the Canada Basin in the Arctic (68.3 ± 8.5 ng g-1 dw), followed by sediments in the Chukchi Sea shelf (49.7 ± 21.2 ng g-1 dw) and Bering Sea (39.5 ± 11.3 ng g-1 dw), while the Bering Strait (16.8 ± 7.1 ng g-1 dw) and Central Arctic Ocean sediments (13.1 ± 9.6 ng g-1 dw) had relatively lower average concentrations. The use of principal components analysis with multiple linear regression (PCA/MLR) indicated that on average oil related or petrogenic sources contributed ~42% of the measured PAHs in the sediments and marked by higher concentrations of two methylnaphthalenes over the non-alkylated parent PAH, naphthalene. Wood and coal combustion contributed ~32%, and high temperature pyrogenic sources contributing ~26%. Petrogenic sources, such as oil seeps, allochthonous coal and coastally eroded material such as terrigenous sediments particularly affected the Chukchi Sea shelf and slope of the Canada Basin, while biomass and coal combustion sources appeared to have greater influence in the central Arctic Ocean, possibly due to the effects of episodic summertime forest fires.

“…Body burdens of PAHs had returned to pre-oiling levels three months post-spill.Arctic.Dunton et al (2014) sampled the benthos of the northeastern Chuckhi Sea to establish baseline conditions for chemical and biological characteristics.Metals, PAHs, and aliphatic hydrocarbons were at natural background levels at nearly all sites sampled, and there is a rich benthic community of organisms with a complex food web.Jӧrundsdóttir et al(2014) documented concentrations of non-alkylated PAHs and inorganic trace elements (arsenic, cadmium, mercury, lead) in blue mussels (Mytilus edulis) and PAH metabolites in cod (Gadus morhua) bile in the Nordic artic and sub-Arctic coastlines to establish background conditions. In general, PAH concentrations and inorganic trace elements were low in mussels (Σ16PAH ranged between 28 and 480 ng/g d.w.) and 1-OH-pyrene was only quantifiable (between.44 and 140 ng/ml bile) in samples collected from the Norwegian coast Harvey et al (2014). documented very low concentrations of PAHs (<1600 ng g-1 dry wt) in the top 0-1 cm of sediments of the Chukchi Sea, and found that common Arctic cod (Boreogadus saida) CYP1A1, GST, and SOD enzyme levels were comparable to baseline levels in other pristine systems.…”

This review covers selected 2014 articles on the biological effects of pollutants and human physical disturbances on marine and estuarine plants, animals, ecosystems and habitats. The review, based largely on journal articles, covers field and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, dredging and disposal, etc. Special emphasis is placed on effects of oil spills and marine debris due in part to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico and the 2011 Japanese tsunami. Several topical areas reviewed in the past (ballast water and ocean acidification) were dropped this year. The focus of this review is on effects, not pollutant fate and transport. There is considerable overlap across subject areas (e.g.some bioaccumulation papers may be cited in other topical categories). Please use keyword searching of the text to locate related but distributed papers. Use this review only as a guide and please consult the original papers before citing them.
